Verification and analysis of a TRNSYS model of a demonstration house equipped with a solar assisted ground coupled heat pump system
Bibliographic record
Abstract
A TRNSYS model of a demonstration house equipped with a solar assisted ground coupled heat pump system (SAGCHPS) has been built. Besides using a built-in vertical ground heat exchanger (VGHE) module in TRNSYS, the model also uses a newly developed VGHE module which considers coupled heat and moisture transfer in ground with variable soil properties and phase change of soil moisture. The TRNSYS model with the new VGHE module (which has three simulation modes) is verified to produce better simulation results than the one with TRNSYS's built-in VGHE module, comparing with the field data of an actual and successful project. Coupled heat and moisture transfer effect in ground plays a more important role than variable soil properties and phase change of soil moisture. However, the result of considering all of them is the best. It is found that a simulation with pure heat transfer in ground (i.e., without moisture transfer and latent heat effect) can be considered in an early stage of a VGHE design. However, for better results and study of long-term effects, coupled heat and moisture transfer in ground with variable soil properties and phase change of soil moisture is recommended.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
